1 143 724. Specification of Letters Patent. Patented J 11 22 1915. No Drawing. Application filed June 12, 1918. Serial No. 773,299.

To all whom it may concern:

Be it known that I, LYMAN DEE Pnrrrr, citizen of the United States of America, residing at Everett, in the county of Snohomish and State of Washington, have invented certain new and useful Improvements in Lubricants, of which the following is a specification.

This invention relates to certain new and useful improvements in lubricating compounds particularly adapted for use to alleviate the possibility of hot-boxes on steam engines and the like and also to diminish to the minimum friction of the working parts of machinery.

The compound is composed of the following ingredients, in the proportions stated: crude petroleum oil, 41 parts; lime water, 41 parts; a preparation of rosin, 13 parts; graphite, 2% parts; paraflin wax, & of 1 part; kerosene, 1 part, red engine oil, 1

part. A mixture formed of theseingredients in the proportions stated results in a highly eflicient lubricant and one which has been proven not to be affected by a wide range in temperature, and is, therefore, a desirable cooling medium for hot-boxes on steam engines and the like.

In making thecompound, an amount of crude petroleum oil (for instance 22 gallon's) is mixed with a like amount of lime water until they are thoroughly incorporated and resemble thick cream. An amount of the preparation of rosin equal to oneseventh of the entire amount (or 6% gallons) is then added to the mass, together with from 8 to 20 pounds of graphite and two pounds of parafiin wax mixed with one quart of red engine oil. The lime water, preferably used in my admixture, is prepared as follows :To 40 pounds of air slaked lime (hydrated preferred) add 25 gallons of soft rain water which, after standing several hours, should be thoroughly mixed and strained through a fine wire screen or gunny cloth to remove all sediment and grit therefrom. The preparation of rosin is formed by adding to 22 pounds of dark colored rosin 21} gallons of kerosene cover it.

which is heated until the mass is melted, when 1% gallons of red engine oil is mixed therewith. After cooling, it is ready for use. The paraffin Wax is cut into small particles and enough red engine oil added to It is then heated and after melting, one-eighth of a teaspoonful of soda is added. The mass should be stirred until cool. The graphite should likewise be mixed with red engine oil. Red engine oil is the best petroleum oil, being the first oil drawn 01f at the refinery. After the gasolene, kerosene and parafiin are drawn off the petroleum is put into a refinery tank and the red engine oil is taken from the top after setting. Such ingredients, when mixed together, will make 400 pounds of lubricant, though it is of course understood any desired amount may be prepared, using the proportions set forth. By omitting certain of these ingredients and combining the balance in difi'erent proportions, I am enabled,

to make an efiicient form of cylinder o il particularly useful as a lubricant about the diflerent parts of machinery. My cylinder oil consists of the following :crude petroleum oil, 24 parts; lime water, 48 parts; a preparation of rosin 4 parts; red engine oil, 24 parts. These formulae result in a lubricant which will not decompose or distil and dry up when subjected to an immediate heat, as in a steam cylinder, or whether it is slow and long continued, as in slides and other bearings, and is therefore superior to lubricants now on the market whichare so affected. I

What I claim as my invention is 1. The herein described lubricating compound consisting of liquid petroleum 42 parts, paraffin Wax 25 parts, graphite 2% parts, lime water 41 parts and a mixture of rosin and refined petroleum 14 parts.

2. The herein described lubricating compound consisting of crude petroleum 41 parts, lime water 41 parts, graphite 2% parts, paralfin wax 25 parts, red engine oil 1 part and a mixture of rosin and refined petroleum 14 parts. 7

3. The herein described lubricating com pound consisting of crude petroleum oil 41 parts lime water 41 parts, graphite 2% parts, para wax 25 parts, red engine oil 1 part and a mixture of 13 parts rosin and 1 part 5 refined petroleumoil.

4. The herein described lubricating compound consisting of crude petroleum oil 41 parts, lime water 41 parts, graphite 2 parts, paraflin wax 25 parts, red engine oil 1 part and a. mixture of 13 parts resin and 1 part 10 kerosene. I

In testimon whereof I aifix my signature in presence 0 two witnesses.
